One of the best ways to spread Truth as you understand it and to spread the love of the Divine is simply to live by example. There is not necessarily a need to describe your beliefs and make people understand why these beliefs might lead to greater peace. Simply by living selflessly, non-attached, and with great love, the Truth will naturally spread to those around you. It is often said by Vedantins that by surrounding oneself with seekers of Truth, one can better
approach Truth. Therefore, there will be a synergistic effect on the approach to enlightenment.
